RVMedia supports GStreamer 0.1, not 1.0:
I've read it, but can you explain why? 0.1 is soooooo outdated...

There are several RVCamera.FFMpegProperty properties that could help.
First, I recommend assigning MaxDelay = 500 000.

And is it possible to pass parameters to ffmpeg?

For example I would like to pass -an and -fast parameters (ffplay.exe -an -fast rtsp://:8554/stream.sdp)

Current version of RVMedia does not allow to pass arbitrary parameters to FFmpeg, only parameters listed in RVCamera.FFMpegProperty.

MaxDelay must be the second property listed in RVCamera.FFMpegProperty in the Object Inspector.

But it isn't there:

What version of RVMedia do you use? New version has much more properties there.

I used version 6.1

Tried version 7, but cant get video stream. I use VideoRecorder project.
Changed in unit SampleCamList the following line (20):

'alias=CAM 1|' + 'url=rtsp://127.0.0.1:8554/stream.sdp|' + 'host=|' + 'port=|' + 'login=|' +

But I get only message: Video stream error.

What has changed in version 7?
Why can't I get the same video stream that works in 6.1?

Do you have FFmpeg available for the application?

Probably, FFmpeg codec does not like some options specified in RVCamera.FFMpegProperty.
Try assigning RTSPTransport = [rvpeTCP,rvpeUDP]

In the next update, we will add a property to turn off all FFMpegProperty options.

Thanks, this helped!

But why these values are not set by default?

We changed this default value in our working version, so it will be changed in the next update.

Hi,

I've tried the "test_ffmpeg" to understand what is happening to my project. But, this tool doesn't run with other dll's but the original deployed by you (see attached release note.txt).

Any way, if I run several instances of this testing tool I can see no delay betwen each live streaming cameras. Why is this not working on the rv-ffmpeg multi camera view example?

Thanks,
